The sign by the F-1 engine.  It reads
    
    
    
    
    
    
    
The Power of Apollo
    
    
    
    The most powerful liquid-fueled rocket engine ever produced, the F-1 engine was
    a critical component in sending Astronauts [sic] to the moon during the Apollo
    program.  Developed under the direction of Werner [sic] Von [sic] Braun, the
    Saturn V rocket was the largest operational launch vehicle ever produced.
    Standing 36 stories high and weighing over 6 million pounds, a cluster of five
    F-1 engines, generating more than 7.5 million pounds of thrust propelled the
    rocket to a speed of 6,000 mph and an altitude of 38 miles in just under three
    minutes.  It was said at the time that, except for a nuclear explosion, the
    launching of the Saturn V rocket was the loudest man made noise ever produced.
    
    
    
    Just one F-1 engine provided as much thrust as all three Space Shuttle Main
    Engines combined!
